i just bought a superchips cortex 1950 tuner and am pretty happy with it. i do have the option of taking it back and getting a credit toward a different tuner. h&s maybe. i cannot do a dpf or erg delete with the cortex. is it worth the extra $300 to get the h&s so I can? looking more for mpg increase than performance. thanks
